PHP for loop

 PHP for loop

PHP for loop


Information :-

1]  The loop is the most complex loop in PHP and is used when the user knows             how often the block should be executed.

 2]  A for loop consists of an initialization statement, a test statement, and an     update statement (an increment or decrement statement).

3]  Loops
 for PHP can be used to iterate over a series of scheduled code.

4] If
 the number of iterations is known you should use it, otherwise use a loop.

5]  This means that you will use a loop when you already know how many     times you want to run a piece of code.


Syntax :-

for (initialization; condition; increment/decrement)

{

// enter code and executed 

syntax  explanation :-

  • initialization :-
  • This part is executed once before the loop starts. It often used to initialize variables.

  • condition:-
  • The condition that is evaluated before each iteration of the loop. If the condition evaluates to true, the loop continues; If it evaluates to false, the loop ends.

  • increment/decrement :- This is done after each iteration of the loop. It is usually used to increase or decrease a number.
